What are Social Networks?
Wikipedia defines

Twitter offers a social networking service, enabling its users to send and read messages called tweets. Tweets are text-based posts composed of up to 140 characters displayed on the user's profile page. Tweets are publicly visible by default; however, senders can restrict message delivery to just their followers. Users may subscribe to other users' tweets – this is known as following and subscribers are known as followers.
Facebook Users may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile. Additionally, users may join common interest user groups, organized by workplace, school or college, or other characteristics.
